Milford Sound has its own microclimate and the weather can change quite dramatically throughout the year (and even throughout the day!). The summer is peak hiking season and you’ll enjoy dry trails, long days and pleasant weather. Plus, the alpine wildflowers will be in full bloom. (Make sure you book ahead - this is the most popular peak season!)
Winter is much quieter, with fewer crowds and sparkling snow settling on the valleys. The shoulder seasons of Autumn and Spring can also be great times to visit. You’ll still enjoy pleasant weather, but there will be fewer crowds than in the summertime. Autumn is best for wildlife, as it’s when seals, penguins and other creatures will be more active.
Remember, this is one of the wettest regions on earth, so always take a waterproof jacket with you.
